The Spaceborne Wind Lidar Mission ADM-Aeolus

, 2012
Measurements of winds throughout the atmosphere are crucial for both numerical weather prediction and for climate studies. Nevertheless, observations of height profiles of the global wind field are lacking. Thus the European Space Agency decided to establish a Doppler wind lidar mission named Atmospheric Dynamics Mission ADM-Aeolus.

Simulation and assessment of spaceborne hybrid Doppler wind lidar, part 1: the spaceborne two-beam stepping direct detection Doppler wind lidar

Optics Express
Accurately measuring wind fields is crucial for weather forecasting, climate and meteorological research, aeronautical flights, and wind resource exploitation. Spaceborne Doppler wind lidar has become an important instrument for observing the vertical profile of the global wind field, with the successful operation of Aeolus.
